Summary
Preoperative computed tomography (CT) can predict outcomes after total colectomy for slow transit constipation (STC). CT helps identify patients likely to experience complications, guiding surgical decisions for intractable STC.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Medical Imaging
Background:
- Total colectomy with ileorectal anastomosis is standard for slow transit constipation (STC).
- Postoperative outcomes after this surgery are variable.
- Predictors of outcomes in intractable STC are not well-defined.
Purpose of the Study:
- To evaluate the utility of preoperative computed tomography (CT) in predicting outcomes.
- To identify predictors of postoperative outcomes after surgical treatment of intractable STC.
Main Methods:
- Retrospective analysis of 22 patients with intractable STC undergoing laparoscopic total colectomy.
- Patients were classified into colonic inertia (CI) and spastic constipation (SC) types based on preoperative CT.
- Comparison of postoperative outcomes between CI and SC groups.
Main Results:
- No significant differences in age, gender, operation time, or blood loss between groups.
- The SC group had a longer postoperative hospital stay.
- Gastric outlet obstruction occurred in 11% of the CI group; pelvic outlet obstruction occurred in 100% of the SC group.
Conclusions:
- Preoperative CT is a useful tool for predicting postoperative outcomes in patients with intractable STC.
- CT-based classification may help anticipate specific complications like gastric or pelvic outlet obstruction.

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

01:25Assessment of the Rectum and Anus
636
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

01:21Drugs for Treatment of Constipation-Predominant IBS
432
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

415
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
